An apparatus for coupling a fishing rod to a rod holder comprises a rod butt holder attached to a fishing rod and selectively and releasably attached to rod holder support arm. The rod holder support arm includes a retaining portion configured to be selectively and releasably attached to the rod butt holder. A latch assembly is coupled to the rod butt holder to releasably secure the rod butt holder to the rod holder support arm.

A control method for a watercraft is used for the watercraft including a device that requires authentication of identification information for activation, and has reading processing, authentication processing, and activation permission processing. In the reading processing, the identification information is read by each of plural reading sections, each of which is mounted on a hull of the watercraft and can read the identification information. In the authentication processing, the identification information, which is read in the reading processing, is authenticated by referring to authentication information. In the activation permission processing, in the case where the identification information that is read by any one of the plural reading sections is successfully authenticated, the device is brought into an activatable state.

A telescoping boat tower (1800), including: a center section (1814); a first support (1802) secured to a first end of the center section, the first support including a first telescoping assembly (1804); and a second support (1808) secured to a second end of the center section, the second support including a second telescoping assembly (1810). The first telescoping assembly and the second telescoping assembly cooperate to raise and lower the center section between a first position and a second position. The center section includes an integrated sun lounge platform (1820) configured as a cockpit cover for a boat, the sun lounge platform including a seating arrangement (1822).

Control system for controlling operations of a marine vessel having a first engine and a second engine is provided. Parity switches are operable to start/stop first and second engine. Each parity switch is actuated for first time to activate remote start/stop control of respective engine. Each switch is actuated for second time to switch respective engine to ON or OFF state. Operator console is communicatively coupled to parity switches to receive first and/or second user inputs. Propulsion control unit is communicably coupled to operator console via network communication channel, first engine control unit of first engine and second engine control unit of second engine. Propulsion control unit receives operational parameters for engines from engine control units and receives first and second user inputs from operator console. Propulsion control unit transmits engine operating signals for operating respective engines in response to first and/or second user input and based on operational parameters.

A system and method for tracking the position of a smart plug on a marine vehicle is provided. Generally, the system and method of the present disclosure are designed to generate indicia used to alert a user of the position of the smart plug on a marine vehicle so that the user may properly position the smart plug on the marine vehicle prior to launching said marine vehicle in a body of water. The system generally comprises a smart plug, a plug sensor, a processor operably connected to the plug sensor, and a non-transitory computer-readable medium coupled to the processor and having instructions stored thereon. In some preferred embodiments, a computing device having a user interface may be operably connected to the processor. At least one sensor of the smart plug collects data that may be used by the system to alert a user to secure the smart plug in the drain hole.
